For me, the album has to be Wanderlust by The Quick Brown Fox. I was never a fan of speedcore before this album, with the most I'd ever heard from the genre being The Big Black (by the same artist). I just saw it as fast and loud music only crafted to make ridiculously hard charts in rhythm games. And then I heard this by complete chance.
One of the best misclicks I've ever made.
Despite following the average speedcore format of blazing drum breaks and utter chaotic sections, this album in particular shows emotion where few other similar artists do. My favourite track has to be the title track, which has those incredibly chaotic sections which I soon came to love, followed by pixelated interludes which have so much charm and drag me back to 2012 when the album released. I then went back to the track I initially dismissed earlier and realised it had the same type of energy, but just evil.
